VEHIOLE-SPRING.

1 ToaZZ whom it may concern:

Be it known that I, LYTLE. R. PARKS, a citizen of the United States, residing at Aurora, in the county of Deal-born and State of Indiana, have invented certain new and use- I ful Improvements in Vehicle-Springs; and

i use the same.

vide a device which will preventthe shocl 20 I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and This invention relates to new and useful improvements in vehicle springs and has for its principal object to provide a simple and eli'ective spring which will take up the shoal; causedby ruts or rough places in the roa Another object of the invention is to profrom being transferred to the frame of the Vehicle to prevent the samefrom being weakened and also to make the riding qu'alities of the vehicle easier.

Another object of the invention is to provide a spring acting on the principle of a lever thefulerum of which is at the end and the load about one fourth of the way from the fulcrum of the force. This allows the wheels to pass over larger objects without transmitting the force of the jarto the body l of the. vehicle.

further object of the invention is to per- 1 m tl of the use of,a longer wheel base withp outimaterially lengthening the chassis and thereby materially improve the riding qualities ofthe vehicle.

Alstill further object of the invention is to I provide a spring which will permit the vbodies tofbe nearer the ground, thereby lowerin the center of ravitv and eliminat- L') b t.

over. a v

Still'another object of the invention is to provide a spring'which may be secured. to any type of vehicle without materially changing the construction thereof.

With these and other objects in view, the invention consists in the combination and arrangement of parts which will be fully set the accompanying drawing, in whi h;

forth in th following specification and in Figure 1.is a side view in elevation of a vehicle body illustrating in detail the springs as they would appear when attached Specification of Letters Patent.

thereto. of the spring.- Fig/3 is. an enlarged detail sectional view taken on line 3 -3 of Fig. l and illustrating the spring suspension in detail. Fi fl is a sectional view taken on line 4i of Fig". 8.

Referring now to the drawings by charao' leaf is extended as at 6 and looped as at? to form the connection to the axle of the ve lllOlQ. The extension 6 1S bent angularly as Fig. 2 is an enlarged detail view illustrated and the remaining leaves of the spring'terminate at varying intervals be tween the angular extension and the clamp designatedby the niuneral 8. This clamp 18 a U-shaped bolt which is arranged to coop erate w th a plate provided with apertures near e:.ch. end in holding the spring leaves in their operative positions. Similar clamps 9 are provided and the ends of the leaves opposite the inclined end are bent back upon themselves as at 10 so as to form a rearward extension '11 which is held in operative position by means of the clamp 12. This rearward extension lies parallel with the remaining portion of the spring and is arranged to bear against the plate 3 hereinbefore mentmned and be secured thereto.

Extending through the loop 7 is the bolt 13 provided with the usual head 14: and

threaded end 15. This bolt is arranged to extend'through the links 16, the upper ends oi": which are pivoted to the bolt 17 which e a-- tends through the loop 18 which is formed on the sleeve '19. This sleeve is a rranged. to surroiind the axle casing 20 as clearly shown in Figs. 3 and d.

It is to be understood that when so desired the axle-casing and sleeve may he grooved to form teeth which coact in holding the sleeve against rotation and. thus prevent any wear on the axle casing. A suitable nut 21 is arof the ordinary construction and comprises 7.

- that such changes ranged to be the end of the bolt which may be adjusted to keep the spring properly lubricated.

It will that in use when the vehicle strikes a rut or rough place in the road the free ends of the spring will be forced upwardly and owing to the peculiar construction of the spring, it will beevident that little or no shock Will be transferred to the body of the vehicle. In this Way it will be apparent, that by placing the springs toward the or toward the center, the Wheel base may be lengthened or'shortened at the desire of the user and a particularly simple and efiicient spring is provided which Will prevent the shock of road travel from being transmitted to the body or chassis of the car.

While in .the foregoing there has been shown and described the preferred embodi-.

ment of this invention, it is to be understood may be mad in the combination and arrangement of parts as will fall Within the spirit and scope of the invention as defined in the appended claim.

threaded on the end 15 of the v be apparent from the foregoing,

ends of .the vehicle Having thus described the invention what is claimed as new, is

The combination with a vehicle having .front and rear axles provided with grooves to form teeth, circular clamping sleeves secured around the axle and provided with teeth on the interior thereof to cooperate with the teeth of the axles to lock the clamping sleeves at various angles on the axles, loops formed on and depending from said sleeves, links pivoted to said sleeves, a bolt journaled in said links, looped around s" id bolt its upper end secured to a body of the ve hicle, and a plurality of leaf springs, one of shorter length than the other secured to the main leaf spring and provided with one of their ends terminating in a line with one end of the main leaf spring.

In testimony whereof I afiix my signature in presence of two witnesses.
